Mumakole anoswika mabhiliyoni mahhanhu okutanga kwebumbiwha kweplanethi yehango ntolo, butjil gwakaguli mudzioshiyeni , kukoti ndoyenda kwelubaka kukobe ndebutjilo pehhugwi kweplanethi ndapasi, kukothama kuti kuzwagwe kwakasiyana kunotjila. Bupaki gwezwidiyo zwehango golakidza kuti butjilo gungabe gwakatanga kumakole angaswika 4.1 bhiliyoni akapinda. Milikila ipapo bulefu gomilika muplanethi yehango ubva kuhhuba, kwakabumbiwa, ndebumilo gwehango kobvumila kuti kube ndebutjilo kakale gupfumile. Mumabvilo ebutjilo gumuplanethi yehango, kose kunopfema kosiyana kakale kondidzana ndebumilo gwako. Kungapinda 99% yezwinhu zwakazwitjila zwisitjipo muplanethi yehango. Kokumbuligwa kuti zwinhu zwinotjila muplanethi yehango nhasi zwakasiyana kwazo, zwimwe azwitozimbgwa. Bengapinda makole ali 7.7 bhiliyoni banhu banotjila muplanethi yehango kakale butjilo gwabo gwakabhatilila mubhayosifiye ndekwakabumbiwa ndeNdzimu.
